Objective To investigate the regularity and clinical significance of cortisol(Cor),adrenocorticotrophic hormone(ACTH),atrial natriuetic peptide(ANP) and interleukin-6(IL-6) changes before and after operation stress.Methods The ACTH,Cor,ANP and IL-6 levels in 18 children with abdominal neoplasms(12 male and 6 female,8 cases with sacrococcygeal teratoma,5 cases with hepatoblastoma,and 5 cases with nephroblastoma) were measured before and after operation(24 hours before operation;4,24,48,and 72 hours after operation).Eighteen children were divided into the study group and the control group.The children in the former group were accompanied with stress ulcer,intestinal obstruction and infection shock or even death after operations,while the children in the later group recovered without any complication.The ACTH,Cor,ANP in serum were measured by radioactive immune analysis(RIA) assay,and serum IL-6 level were measured by enzyme linked immunosorbent assay(ELISA).Results In 2 groups,serum levels of ACTH,Cor,ANP,IL-6 increased significantly 4 h after operation.The changes in ACTH and ANP were similar in 2 groups.Cor in the control group reached its peak 24 h after operation,and then decreased gradually to the pre-operation levels 72 h after operation;IL-6 reached its peak 4 h after operation,and then decreased slowly.It was still at a high level in 48 h after operation,and then decreased to pre-operation levels 72 h after operation.But serum Cor,IL-6 in the study group slightly increased 24 h after operation,and were apparently higher than those in the control group(Pa

Objective:To investigate the morphology character of sagittally unstable intertrochanteric fractures and reduction methods.Methods: A retrospective study was used to analyze the clinical data of sagittally unstable intertrochanteric fractures cases,which were treated with proximal femoral nail anti-rotation (PFNA) fixation from March 2009 to June 2016.In the study,36 cases were followed up completely,in which 17 cases accepted open reduction,and the other 19 cases accepted minimally invasive reduction.The operation time,amount of bleeding,the fluoroscopy times,postoperative radiographic measurements,such as tip-apex distance (TAD) and sliding distance of the spiral screw,and hip Harris scores were analyzed.The morphology character of the fractures was documented and investigated.Results: The average follow-up time was 15 months.The amount of bleeding of the open reduction group was (170.5±19.7) mL,and the amount of bleeding of the minimally invasive group was (54.7±12.5) mL.The amount of bleeding of the minimally invasive group was significantly less than that of the open reduction group (P<0.001).Between the two groups,there were no significant differences in other evaluation parameter,including operation time (P=0.054),the fluoroscopy times (P=0.053),fracture healing time (P=0.305),postoperative radiographic measurements,such as TAD (P=0.317) and sliding distance of the spiral screw (P=0.206),and hip Harris scores (P=0.459).In regard to morphology character of the fractures,the proximal anterior unstable fractures with separation displacement were more common than the proximal posterior unstable fractures with impaction.The characteristic feature of the proximal anterior unstable fractures was the proximal anterior and medial long oblique fracture,and a V shape cortical defect in the distal fracture fragment on the externally rotation X-ray.Conclusion: Sagittally unstable intertrochanteric fractures can be divided into the proximal anterior unstable fractures with separation displacement,and the proximal posterior unstable fractures with impaction.The two types have their own morphology character individually.The reduction should be performed by minimally invasive techniques.

Objective To study the immunological regulation of Nasal Healing Spraying Agent (NHSA). Methods Test models were setup by irradiation. The models were administrated with NHSA by lavage and immune adherence of red cells was tested by chaplet experiment with blank and positive control. Results NHSA could increase Red Blood Cell-C3b Receptor Rosette (RBC-C3bRR) and reduce Red Blood Cell-Immune Complex Rosette (RBC-ICR) in mice. Compared with blank control group, the results in the high dose group and middle dose group were statistically significant (P<0.01). The result also showed that NHSA could elevate the quantity and activity of Red Blood Cell-C3b Receptor (RBC-C3bR) and reduce the Immune Complex (IC) to enhance the red cell immune function in mice effectively. Conclusion NHSA could elevate the RBC immunity function in mice and increase immunoregulatory function.

Objective To investigate the high resolution CT (HRCT) findings of pleura invasion of lung adenocarcinoma (stageⅠ) presenting as mixture ground glass nodule (mGGN).Methods 20 cases of lung adenocarcinoma presenting as mGGN were confirmed by pathology.The correlation of those cases with pleural adjacent relation and the relation between the maximum diameter and pleural invasion were analyzed retrospectively.Results (1)The classification of mGGN adjacent to the pleura relationship:type Ⅰ,typical and atypical pleural retraction sign,10 cases of this type did not show pleural invasion;type Ⅱa,the mGGN contacted pleural for ground glass opacity,4 cases of this type showed no pleural invasion;type Ⅱb,the mGGN contacted pleural for solid elements,6 cases of this type were with pleural invasion.(2)The difference of the maximum diameter of mGGN in groups pleural invasion and non-invasion was not significant statistically (P=0.694).Conclusion The mGGN contacted pleural for solid composition is a reliable sign in diagnosis of pleural invasion.

Objective The questionaires of the ONFH aegers who were hospitalized in Kanggu hospital,during 2005-2008 ,were collect-ed to evaluate the therapeutic effects of acupotomy by proper statistical methods. Methods Four indexes according to the criteria of Therapeutic effect of adult ONFH recovery and reconstruction (ZHAO Dewei, 1996) were measured to evaluate the effect of the treatment. Results Monofac-torial analysis showed that the treatrnent was effective,but some phenomena could not be correctly explined in specialized field. This problem was re-solved appropriately by structural equation model(SEM). Conclusion By the method of SEM, the confounding factors could be better controlled and the evaluation was more reliable.

Objective To evaluate the curative effect and security ofYangxue-Qingnao granules on posterior circulation ischemia.Methods 52 patients with posterior circulation ischemia from September 2012 to January 2014 in Remin hospital of Wuhan Universityk, were randomly recruited into a control group and a treatment group, with 26 cases in each group. The control group was only treated with flunarizine HCL and Betahistine Mesilate Tablets, while the treatment group was givenYangxue-Qingnao granules based on the control group. The change of clinical symptoms, TCD and cervical vascular ultrasound were observed before and after the treatment.Results After the treatment, the total effective rate of treatment group was significantly different to the control group (96.2%vs. 76.9%;χ2=4.127,P=0.042). The changes of blood flow velocity of vertebral artery, basilar artery and posterior inferior cerebellar artery were all decreased after the treatment in both groups (tvalue in the treatment group were 20.624, 13.773, and 9.485 respectively,t value in the control group were 13.203, 9.550, and 5.655, respectively, allP<0.01), besides such decreases in the treatment group were better than the control group (allP<0.01). After the treatment, the condition of carotid IMT decrease was significantly better in the treatment group than the control group (the number rate of IMT decrease was (96.2%vs. 69.2%;χ2=5.318,P=0.021).ConclusionYangxue-Qingnao granules can obviously improve the blood flow velocity and the thickness of IMT in patients with posterior circulation ischemia. The short-term curative effect is obvious.

Objective To investigate the effect of growth differentiation factor 5(GDF-5)on expression of gap junctional protein,connexin 43,during ehondrogenic differentiation of bone marrow sternal cells(BMSCs)in vitro.Methods BMSCs were isolated from mouse bone marrow and cultured in vitro.The cells in passage 3 were chosen to be induced into chondrogenic differentiation.After induction for 72 hours,TypeⅡcollagen protein was examined by immunocytochemistry and the sulfate glycosaminoglycan was measured by Alcian blue staining.With induction for 24,48 and 72 hours,the proliferation effects of BMSCs were investigated by MTT assay;connexin 43 mRNA and protein were examined by RT-PCR,western blotting and immunocytochemistry respectively at different time points during induction.Results According to MTT assay,GDF-5 had no effect on the proliferation of BMSCs at different time points of induction;RT-PCR,western blotting and immunocytochemistry showed that GDF-5 could promote expressions of connexin 43 mRNA and protein at different times during induction.After 72 hours of induction,immunocytochemistry showed expression of TypeⅡcollagen protein,and AIcian blue staining of proteo- glycan revealed deposition of typical cartilage extracellular matrix.Conclusion GDF-5 can enhance chondrogenic differentiation of mouse BMSCs in vitro by up-regulating the expression of gap junctional protein,connexin 43.
